The outer tank is the key facility to ensure the safety in the LNG storage tank, prestressed tendon construction process is an important part for establishing structure system, so it is of great significance to study the establishing process. Based on some LNG storage tank, this paper chooses a large general finite element software ANSYS and establishes the finite element solid model, analyzes the concrete stress state, storage tank deformation and prestressed tendon stress state, which proves good mechanical performance and the stress is under control during prestressed tendon construction.
